Hi,
what is the difference between
a) select * from server.database.owner.table where [id] =3D 15
and
b) select * from openquery(server, 'select * from database.owner.table = where [id] =3D 15')
I have the effect that b) gives the correct result while a) has zero = hits.
Can anybody help?
Jochen

That's strange. I hace just tested it on my box and it works fine
As far as I know when we use OPENQUERY SQL Server opens an addition =connection to retrieve the data ( I am not sure for 100 percent)

Here are some additional information:
SQL 2000 SP3 - Build 8.00.818
The database is merge replicated, but the effect is still there when I =delete all replicational stuff.
Some more effects:
[id]-clumn has data from von 1 - 8000. With
select * from server.database.owner.table where [id] < 6000
the result table ist still empty. With
select * from server.database.owner.table where [id] < 6001
all rows are given back with [id] < 60001. Further it is strange that =the server answers with correct results when I start the query on =itsself (as whith OPENQUERY).

to see what is submitted to the other DBMS in both cases...

In this case OPENQUERY should return the same result as the straight =query...
Do as Tibor says, and check the query plan for both to see if you can =learn anything from that...Also check/play with the collation order =options on the linked server(although that should not matter with an =integer comparison.)
